我有一个程序，我正在重写成Node.js。它是一个Python程序，base64对其进行解码和解压缩。
下面是Python的原始代码：

import base64
import zlib

def decode_str(data: str) -> str:
    base64_decoded = base64.urlsafe_b64decode(data.encode())
    decompressed = zlib.decompress(base64_decoded, 15 | 32)
    return decompressed.decode()

我想在下面的字符串上使用它：

当我用Python运行它时，它运行得很好，但是当我用JavaScript重写它时，它出错了，代码如下：

const zlib = require('zlib')
let b64decrypt = (encodedData) => {
    return Buffer.from(encodedData, 'base64').toString();
}
let decrypt = (ls) => {
    let fin = b64decrypt(ls);
    return zlib.gunzipSync(fin, { windowBits: 15 | 32 });
}
let l = 'H4sIAAAAAAAAC5VV25HDIAxsSM4gCfGY-7oaUgAFXAtX_EngC5DYJsmMUeLVrh4I8nPnBFhcIX1YH8RCIgWpGa7Glw1LKOicK7FgQbElqXsq-PsBHU_p6Kg074VEPpQwn0Z4S4SK8c9zye_JyKnMh_mEhdC6uXTIjhVgZetymcMhHQO-FZwP2PDzjQzOjDQTmvGga_se25vdJDN3zvUXAeraBCrw7evaUHTNILgvBFJLEDMwYIggEeyFwBYgwJadOqgaeVAPgnRLUUnZGQmzKCtoihzUR7BSLSBZJI2T9QNs8ZIoQfS4PEI2dpQa8oYGYAz-CaGGjBTtHYjF02wPeAMcZvJQY77ZO3utlW08lLY7J3P2jv-j7C35b8ZEQfbBlJKFFxnaAbGKaS-GLoSk_YNgLYqu7sEk4EMXiCaQDgS2S4XcFcQUwqcKQl2BTcGvi2gzsWfAnZ9tJDaUPhWDzqPhtmsvW1vb3V1oHpgnNF2iconSOng9IZsW_FA4H4iJkvN0qK4IaZkGY6-DB3Q_ASPsp7PRkEE7jWfjBY0nkdkvXd7I37_kP6J4iW7X8NkW77mldYV46GL_M-pTB3sa71qNu4me23bdxdoBuwXzcMF64pcbNl8NQ4v0fCUfXca7f5DpenPTjPJZlHouOHKvdzWlXupYe-7bcEb5AxMHn1whCQAA';
console.log(decrypt(l))

我试着运行它，它给了我这个错误：

RangeError [ERR_OUT_OF_RANGE]: The value of "options.windowBits" is out of range. It must be >= 8 and <= 15. Received 47

当我删除windowBits选项时，它给了我这个错误：

Error: incorrect header check

如何解决这个问题？
